This invention relates -to harvesters and more particularly to corn havesters having mechanism for gathering and cutting stalks.

An object of the invention is to provide a novel form of cutting mechanism for a harvester. l K 1 Another object ofthe invention is to provid-e a Vharvester having a cutting mechanism which will leave practically none of lustrated in Figure 1 g the stalks above ground after the machine has traversed a row of stalks.

Other objects of the invention will appear as the following description proceeds.

An illustrative embodiment of the invention is shown in the accompanying drawings, in which: .Y

Figure 1 is a perspective view of the harvester showing the novel arrangement of cutting mechanism and supports therefor;

Figure 2 is a detail perspective View of the cutting mechanism and its supports il- Figure 3 is a. detail plan view of theauxiliary frame carrying the cutting mechanism; and n Figure 4 is a plan View of the entire ma# chine.

main frame of the machine consists of a forward part having a draft appliance 11 at its forward end and supporting wheels 12 at its rearward end. The rearward partv 13 ofthe frame is mounted on the axle 14 and has forwardly extending and forwardly di- 'verging parts 15 and 16, which are positioned beneath gathering devices including apair of gathering boards, one of which is shown at 17. is a shield 18 and an upper Agathering chain 19.V An intermediate gathering chainstantially in contact therewith, .and it also provides space within which a floating auxillary frame may have vertical movement as it rides along the ground.

`under different conditions. K

The cutting .mechanism carried by the.

Above each gathering board The floating auxiliary frame comprises vside members 26 and 27 pivoted at their forward ends at 28 and 29 on the frame members 15 and 16, respectively; As illustrated in Figure 2 of-.the'drawingathe members 26 and 27?V are free to have vertical movements within the limits imposed by the frame members 15v and 16, and a lift mechanism comprising a chain 30, a rockshaft .31, a crank arm `32,and a hand lever 33. This A:lift j arm encounters a stop 34, her-ein shown as aV member joining the `frame Yparts15 and 16.

The floating auxiliary frame carries at its sides iatywide, ground vengaging runners 35` and 86. v As shown, these runners are pivoted upon the members 26 and 27 at their forward ends and are adjustably mounted upon Vthose members at their rearward ends by securing 75 devices 37 and 38. f This arrangement of elei ments enables the operator of the machine to Referring to Figure 1 of the drawings, the

cut stalks substantially at the' ground `-level lioatingauxiliary framev comprises a forwardly extending oscillating arm 39'hereinv shown as having an upright trunnion V10 formed atitsrearward end. This trunnion isjournaledin a bracket .111,` which isrigidly.

mounted on the members 26 and v27. This bracket also acts as ia journal,for one endv of a laterally extending` stay rod 42 journaled Aat one end on the rearward part ofthe mainf frame. ata position indicated by43 in'F igvure 1 of the drawings. It acts to maintain tion transversely of theharvesterfduring its vertical movements.

TheV forward end of theV oscillating 39v carries a. cutter comprising a head 111 carry-4 ing' cutter sections 45 and mountingv a pitymanfpost'46.` This post'is rotatably-received by. one end of a pitman 1175 the other end of'l which is'journaled upon a crankipinh48 formed upon a crank arm or crank wheel 49 the main frame and it carries at its upper end a flywheel 52. It is driven by -a beveled `pinion 58 connected to the shaft through a slip clutch 54 normally held in driving position by a spring 55.

The pinion 53 meshes with a driving ygear'A 56 fixed upon a driven shaft 57 which is pro'-V into a gear casing 59 and has a pinion 60 therein meshing with a gear 61 xed on the counter-shaft 62. This ,counter-shaft, is driven from a main counter-shaft 63 by sprocketgearing 64,;Inv the drawings the shaft 63 is shownv as driven bygearing 64 from 'a main driving shaft 65, which receives -0` ports`66 and 67 secured to thermain frame.

The shaft 65 is'journaled-in uprightv sup- -The upwardly bowed portions 23 vand 24 ofthe frame parts 15 and 16 also provide an advantageous mounting for the sprocket of the gathering chain`2l-.f- This sprocket is shown aspositioned beneath the .portions 23 and 24 and located at 68,thus enabling the gathering chain 21 to operate ata sufliciently' low position so as to engage the butts of the stalks and positively move them upwardly onthe butt pan 69. The lowerfendfofthis butt pan is .extended toward-the cutter, itsv extreme lowerend constituting a pivoted section 7,0 substantiallyin contact with the cutter head '44;

'While thevinvention has` been described with reference to a particular machine, itis to be understood that'it is not limited thereto, but is rather of a scope commensurate with the scopeof the sub-'joined claims.

' What is claimed as new is: l fr 1.-A harvester comprising, in kcombination, stalk gathering devicesfproviding a stalk passage-way, a stalk cutter oscillating across the passage-way, a main frame carryuing the gathering devices, a floating auxil-` iaryframe carried by the mainframe in position todrag along the ground beneath the v gathering' devices, means carried by the auxiliary frame toloscillatably mount the cutter d i d b thermain; thereon an means Carme y ata point spaced from its pivot and adJaframe to oscillate the cutter.
